Design and simulation of temperature measurement circuit based on LabVIEW and Multisim

This paper systematically introduces the principles of temperature measurement circuits and the structure of temperature measurement based on virtual instrument. The design and simulation are based mainly on Multisim and LabVIEW. The validity of the circuit design is tested. A virtual temperature display instrument is designed by using LabVIEW8. A detailed design process of temperature measurement circuit is also given.
